3. PROTECTION
3.1 Over current protection
3.2 Over Temperature Protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V outputs from
exceeding the values shown in the following Table. If the current limits are exceeded the
power supply shall shutdown and latch off.
The power supply will be protected against over temperature conditions caused by loss of
fan cooling or excessive ambient temperature. In an OTP condition the PSU will shutdown.
When the power supply temperature drops to within specifide limits, the power supply shall
restore power automatically. The OTP circuit temperature drops to within specifide limits,
the power supply shall restore power automatically. The OTP circuit condition.
3.3 Over-power protection
The power supply will be shutdown and latch off when output power within 110~160% of
rated DC output.
Note: Assurance machine can work at low voltage,full load won't damage machine.
3.4 Under voltage protection.
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state
when +12V,+5V & +3.3V outputs under 85% of it's maximum value.
ST60F-TI
When the logic level "PS-ON" is low, the DC outputs are to be enabled.
When the logic level is high or open collector, the DC outputs are to be disabled.
